[Dune] Question about Dune-alugrid license

[FOCHESATO Christophe 603260]

Thank you for the answers. Indeed in the long term, we will distribute the software, so we cannot rely on the Dune-alugrid.

We saw that ug grid could be used but it does not match our needs for now since it does not provide codimension-1 entities.

Our idea was the following: rely on Yaspgrid in a first  time, but we were hoping to keep the possibility to use an unstructured grid in the future, and so to minimize the dependence to Yaspgrid as much as possible if we can. We were thinking about alugrid for that.

I imagine this is still possible but there will be more work to do with ug grid since we would have to implement the missing functionalities, isn't it?

Dear Christophe,
licensing is such a nice topic. Everybody has an opinion. Myself included; I am not a lawyer.

It strongly depends on what you want to do. You have to explain how you want to use Dune.

As far as I understood it:
1) You can do whatever you want, if you keep the software to yourself within your institute.
2) You can publish your codes under whatever licence you want.
3) You have to be careful, when you share binaries. This includes selling your software in a compiled version, offering binaries for download or packaging RPMs / DEB packages which includes binaries.

If you do not 3), you can ignore GPL/LGPL/GPL+runtime-exception 1/2/3/+.

As a consequence of 3) Debian has no alugrid package and openSuse's dune-grid package does not use the alugrid package.

So it depends on your use-case whether the differences in licensing are relevant for you. In my perception most academic users choose to do not distribute their code as binaries and are fine with that.

Bye
Christoph
